Meeting Abstract S8.7 Thursday, Jan. 6 Beyond maternal effects on avian development: embryonic responses to the environment.ail REED, W.L.*; CLARK, M.E.; North Dakota State University, Fargo wendy.reed@ndsu.edu Embryonic growth and development are impacted by environmental conditions. In avian systems parents often tightly control these environments through egg provisioning and incubation behaviors. Parents can influence offspring embryonic development […]

The role of pre-existing plasticity in adaptive evolution
Meeting Abstract S8.1-2 Monday, Jan. 6 08:30 The role of pre-existing plasticity in adaptive evolution SERRATO-CAPUCHINA, G.A.; PFENNIG, D.W.*; Univ. of North Carolina, Chapel Hill; Univ. of North Carolina, Chapel Hill dpfennig@unc.edu In order for adaptive evolution to occur, phenotypic variation must be present on which selection can act. Yet, relatively little is known about the source(s) […]
The importance of fluctuating temperatures for offspring phenotype in turtles with temperature-dependent sex determination
Meeting Abstract S8.2-1 Monday, Jan. 6 10:30 The importance of fluctuating temperatures for offspring phenotype in turtles with temperature-dependent sex determination BOWDEN, RM*; PAITZ, RT; Illinois State University; University of Illinois rmbowde@ilstu.edu In species with temperature-dependent sex determination (TSD), the temperatures experienced during incubation are correlated with the resultant sex of the offspring. It has also been […]
The evolution of within- and among generation phenotypic plasticity in natural populations of Daphnia
Meeting Abstract S8.1-4 Monday, Jan. 6 09:30 The evolution of within- and among generation phenotypic plasticity in natural populations of Daphnia WALSH, M.R.; Univ of Texas, Arlington matthew.walsh@uta.edu Many environmental forces (invasive species, climate change, habitat loss) threaten native biodiversity. The mechanisms that permit persistence, such as the ability of organisms to evolve genetically or alter the […]
Plasticity and constraints on the evolution of body shape Phenotypic integration in locally adapted Trinidadian guppy populations
Meeting Abstract S8.2-2 Monday, Jan. 6 11:00 Plasticity and constraints on the evolution of body shape: Phenotypic integration in locally adapted Trinidadian guppy populations HANDELSMAN, Corey A*; WALKER, Jeffrey A; GHALAMBOR, Cameron K; Colorado State University; University of Southern Maine; Colorado State University chandelsman@gmail.com A major problem in evolutionary biology is to understand the dual nature of […]
Physiological mediation of integrated phenotypes From plasticity to evolution
Meeting Abstract S8.3-2 Monday, Jan. 6 14:00 Physiological mediation of integrated phenotypes: From plasticity to evolution SWANSON, E.M.*; SNELL-ROOD, E.C.; Univ. of Minnesota, Twin Cities; Univ. of Minnesota, Twin Cities eliswanson@gmail.com Hormones are important mediators of phenotypic responses to environmental variation at both the developmental and the population level. In addition, hormones commonly influence multiple traits simultaneously; […]
Ecological variation and hormone-mediated plasticity in Death Valley’s pupfishes Insights into the dynamics and distinctiveness of phenotypic diversity
Meeting Abstract S8.3-3 Monday, Jan. 6 14:30 Ecological variation and hormone-mediated plasticity in Death Valley’s pupfishes: Insights into the dynamics and distinctiveness of phenotypic diversity LEMA, S.C.; CalPoly, San Luis Obispo slema@calpoly.edu Phenotypic variation is generated via the complex orchestration of interacting factors that an organism experiences during development. Studies of hormone signaling systems can play a […]
Early-Life Programming of Neuroendocrine Function by the Immune System Plasticity or Autoimmunity due to Biome Depletion
Meeting Abstract S8.3-1 Monday, Jan. 6 13:30 Early-Life Programming of Neuroendocrine Function by the Immune System: Plasticity or Autoimmunity due to Biome Depletion? BILBO, S.D.*; WILLIAMSON, L.L.; PARKER, W.; Duke University; Duke University; Duke University staci.bilbo@duke.edu Immune molecules have a powerful impact on neuroendocrine function during health as well as sickness. Microglia are the primary immunocompetent cells […]
Diversity of Phenotypic Plasticity
Meeting Abstract S8.3-4 Monday, Jan. 6 15:00 Diversity of Phenotypic Plasticity CREWS, David; Univ of Texas, Austin crews@mail.utexas.edu Developmental plasticity has the potential to generate novel phenotypes. These may be nuances or wholesale transformations, adaptive or maladaptive. The environment dictates such outcomes. The generation of phenotypes is usually in the dimension of epigenetics and not by traditional […]
Developmental plasticity in amphibians mechanisms, adaptations and constraints
Meeting Abstract S8.2-3 Monday, Jan. 6 11:30 Developmental plasticity in amphibians: mechanisms, adaptations and constraints CRESPI, Erica J; Washington State Univ. erica.crespi@wsu.edu It is well known that environmental conditions during early life stages can alter specific developmental processes that influence phenotypic expression and performance throughout the life of an animal. Fluctuating levels of environment-responsive hormones, such as […]
